the hydraulic system design

With the development of hydraulic technology, engineering machinery hydraulic drive system has been very common. From a technical point of view, any kind of hydraulic transmission system shall meet the reasonable design, simple structure, easy to use, high efficiency requirements. Hydraulic system will have a direct impact on the performance of the pros and cons of construction machinery, hydraulic steering systems use this article on Troubleshooting common to talk about some of the knowledge and practices. Hydraulic steering system a heavy steering a) if the fast forward or slow rpm steering wheel are heavy and no pressure, oil level may be low, hydraulic hose assembly the oil viscosity is too large or the valve body check valve failure. First check the oil tank and hydraulic oil viscosity, if the oil level is lower than the standard height of adding hydraulic oil, oil viscosity too should be replaced as appropriate viscosity hydraulic oil, such as the viscosity of the oil level should normally decompose steering. If the body of the check valve ball is lost then load the new ball, if the ball stuck in the dirt should be cleaned, if the one-way valve sealing tape poor contact with the ball ball impact of the application, making it reliable sealing. 2) If you turn the steering wheel slowly turn the steering wheel light or fast sink, it may be caused by insufficient fuel supply pump. And the viscosity of the oil level should be checked under the premise of a suitable pump is working properly, or if a small amount of hydraulic oil pressure is low and should be replaced repaired. 3) If the empty load or light load shift light and heavy-duty steering heavy, it may be lower than the pressure relief valve block valve working pressure or relief valve core is dirt stuck or banjo fitting spring failure or damage caused by seals . Should first adjust the working pressure relief valve in the purge relief valve adjustment is ineffective when the decomposition, such as spring failure, damaged seals should be replaced. 4) If the hydraulic cylinder when turning the steering wheel does not move when you move and the issue of irregular sound, it may be the steering system or steering hydraulic cylinder with air leakage caused by too much. Open the tank cap should check whether there is a bubble in the tank, if the first check for leaks at the suction tank, and then check the pipe connections are intact, and the exclusion of air in the system. Such as when the hydraulic cylinder is still not moving when moving piston seal condition should be checked, if necessary, replace the seals.

The correct approach is the tube end what kind of connector body, connecting terminal corresponding with the same type of connector is pre-installed, so can maximize avoid leakage problems. ② pipe end should be flush. After sawing the pipe should be ground flush on the wheel, and other tools, and deburring, cleaning with high-pressure air blowing before use. When ③ preinstalled, should be kept coaxial tube and connector body, if the tube is too large can cause skew seal failure. ④ preloaded force should not be too much of the inner edge of the ferrule just embedded in the outer wall of the tubes, ferrules should not have significant deformation. When making pipe connections, then the provisions of the tightening force assembly. ф6-1 ferrule tightening force is 64-1 15n, 16фmmr 259n, ф18mm to 450n. If, at the pre-card sets severe deformation, it will lose seal.

Pipe joints leak prevention

In the hydraulic banjo fittings system, whether it is the metal fittings or hose connectors are prone to leakage problems. For card sets of pipe joints, mostly due to the pipeline by large external force or impact, so that the card sleeve loose or deformed pipe ends and cause leakage, you should check whether the card holder out of round, edge or without defects, whether the pipe end in good condition and the extent of the compression ferrule nut, but also the elimination of external piping. For flared fittings, mostly due to excessive flaring, undesirable quality or dismantle flaring resulting deformation or cracks caused by leaks, this time can be re-flared front end truncated. If the top male and female cones pressure seal, the leakage is mostly due to two cone damage, it is available for cone grinding abrasive sand. In some use "о" by the end face or outer ring sealed case, the leakage following reasons: "о" ring deformation caused by aging or leakage; "о" ring assembly is not in place, so that the two-plane connection When the pressure is uneven or "о" ring is cut causing leakage; "о" ring uncompressed, insufficient amount of elastic deformation caused by leakage; "о" mouth-ring groove stop too deep and cause leaks. In this regard, the need to re-select the same diameter and cross-sectional coarse "о" rings, can also be sealed with a flat opening slot stop cutting or grinding, to reduce the groove depth of mouth only, so "о" ring has sufficient elastic deformation (compression in general should be between 0.35-0.65mm). For the use of oil sheet, wool felt, soft steel board, combined sealing gasket or pipe joints leak sealant, No matter what the material, you should first check the seals without damage, deformation, aging and rough through the large, etc. and then take the appropriate measures.

Hydraulic valve works

Hydraulic valve works
1) Industrial (also known as fixed equipment, which is relative to the walking mechanical terms) is generally 4-pass valve, that four main ports: pressure oil imports P, load ports A and B, leading to the tank back to the oil port T. The rest of the control port, load pressure LS port, drain port and so can not be calculated in a few pass inside.
2) Those who need the pilot to control the oil on the main stage of the elements, such as reusable hydraulic hose fittings, the pilot oil sources are present and how to deal with the issue back to the oil. This is the performance of hydraulic quick couplers technology flexibility, giving users stay out of the room according to the actual needs of the system for selection. Here:
X-- control oil inlet from the outside of the main system (called external control, if from P mouth, said internal)
Y-- control oil taken directly to tank port (called outside back (leaks), if returned to T port, said inner back (inside vent))
L-- valve leak within the oil tank alone brought back the oil port
3) Incidentally, processing pilot oil can be reasonably combined as required:
External control, outside back; external control, internal back; internal and external back; internal control, internal back.
4) Incidentally, for L mouth leaking oil, outside the pilot oil return, must lead directly back to the tank (or through the filter), should never be brought together to the main return oil tank T ports be brought back. This situation is even more sensitive in the ratio, the servo system.

The use of performance and service life
